Privacy Policy
What Callvenge collects, why, and where it goes — in plain language, matched to the actual code.
01Overview
Callvenge is a call-screening app: it blocks numbers you choose, shows you carrier and line-type information about who's calling, and helps you report unwanted calls to the right consumer-protection agency. It runs entirely on your device — there is no account, no sign-in, and no server holding a copy of your data.
The short version: your call history, block list, and notes stay on your phone. The only information that ever leaves your device is described in full in Section 3 — and even that only happens if you've turned the relevant feature on.
02Information we collect
All of the following is stored locally, in the app's own private database on your device:
- Screened call details — the phone number, timestamp, and whether it was blocked or let through, captured through Android's call-screening system at the moment a call arrives.
- Caller-ID verification status — where your carrier supplies it, whether the caller ID passed carrier-side (STIR/SHAKEN) verification.
- Numbers you add to your block list, and any reason you attach to them.
- Notes you type about a specific call, if you choose to add any.
- Your selected state, used only to show you the right regional consumer-protection agency when reporting a call.
- Your subscription tier (Free or Premium) and how many carrier lookups you've used this calendar month.
03Shared with third parties
Callvenge shares data with exactly three outside parties, each only in the specific situation below:
| Who | What's shared | When |
|---|---|---|
| NumVerify (operated by apiLayer) | The phone number of a screened call, to look up its carrier and line type | Only if a NumVerify API key has been configured for this build — without one, no lookup happens and nothing is sent |
| Google Play Billing | Nothing initiated by Callvenge beyond the purchase itself — Google Play processes the entire transaction | Only if you choose to purchase Premium; Callvenge receives a product ID and purchase token, never payment or card details |
| A consumer-protection agency (FTC, FCC, or your state's agency) | Whatever you personally paste and submit on that agency's own website | Only if you tap "Report" — Callvenge copies a plain-text summary to your clipboard and opens the agency's own site; it never auto-submits anything on your behalf |
Each of these third parties is governed by its own privacy policy for the data you send it, not this one.
04What we don't do
- No analytics SDK, advertising SDK, or crash-reporting SDK is included in the app.
- No account or sign-in system exists, so there's no name, email, or password to collect.
- No access to your contacts, SMS/MMS messages, or your phone's call log — only the single incoming number a screening decision needs, handed to the app in the moment by Android's own call-screening system.
- We never sell, rent, or otherwise share your data for advertising purposes.
05Storage & security
Everything in Section 2 is stored in a local database inside the app's private storage, which other apps cannot read. Data only leaves your device in the three specific cases in Section 3, or when you personally use the CSV export feature and choose a destination (email, Drive, etc.) through Android's own share sheet — that choice, and that data, is entirely under your control each time. The one automatic network request Callvenge makes (the NumVerify lookup) is sent over HTTPS.
06Your choices
Because nothing is mirrored to a server, you're always one step away from deleting all of it: clearing Callvenge's storage or uninstalling the app (both in Android's own Settings app) erases every screened call, block-list entry, and note immediately and completely. There's no separate "request my data" or "delete my account" process to go through, because there's no account and no off-device copy to delete.
07Permissions
| Permission / role | Why Callvenge requests it |
|---|---|
| Call Screening role | Lets Callvenge see an incoming number long enough to decide whether to block it — the core feature of the app. |
| Notifications | To tell you about a screened call and to send an occasional reminder if you have blocked calls you haven't reported yet. |
| Internet & network state | To perform the optional carrier/line-type lookup and to check connectivity before attempting one. |
08Children's privacy
Callvenge is not directed at children and is not knowingly used to collect information from anyone under the age of 13 (or the equivalent minimum age in your region).
09Changes & contact
If this policy changes, the effective date at the top of this page will be updated. Questions about this policy or Callvenge's handling of data can be sent to privacy@callvenge.com.
